Library: PLCopen Safety FBs

Identification of the library described here: PLCopen Safety FBs, 3.5.18.0

Basis: PLCopen TC5: "Safety Software, Part 1: Concepts and Function Blocks", Version 2.01, February 25, 2020

The PLCopen function blocks (prefixed with SF_) have been defined by the PLCopen organization together with its members and external organizations dealing with safety-related aspects. These function blocks are certified and as a result reduce the time and costs in the development, verification, and acceptance of a safety application. Similar to a logical wiring, the blocks can be linked to each other by logical operations. Thus, important components of a safety application can be created quickly and without much programming effort.

For information describing the individual PLCopen FBs in more detail, see the PLCopen "Technical Committee 5 – Safety Software" specification version which is current at the time of certification.
